    I have an early build Challenger Hellcat (Dec 2014) that qualifies for the TCM flash. I have been reluctant to have it done, but in sport mode in full auto, the trans doesn't shift out of first sometimes before the redline is hit where the fuel is cutt-off. This usually happens when traction is broken, but in track mode the trans always shifts up to second with no loss of power, hesitaion, or cut-out........even if you have broke the tires loose and tach up really fast....I wonder if the flash will eliminate the sport mode snafu.

    I like the harshness of the trans shifting and am a bit fearful that the trans shifting characteristics may change to a different feel if I have the software update performed. Can readers that have had the flash please chime in ???

    Do the flash, all is good and yes, track mode will continue to bang those shifts just fine. Not to mention the other modes are not bad either.
